Update of bug #55354 (project octave): Status: None => Fixed Open/Closed: Open => Closed _______________________________________________________ Follow-up Comment #2: Thank you for the detailed bug report and example. Fortunately, this bug has already been fixed in more recent versions of Octave, so all you need to do is to upgrade your Octave installation. In Octave 4.2 and newer: >> f = @(x) atan (x) ./ (1 + exp (-x .^ 2)); >> fd = complex_step (f, 2) fd = 0.2746237281548576 _______________________________________________________ Reply to this item at: <https://savannah.gnu.org/bugs/?55354> _______________________________________________ Message sent via Savannah https://savannah.gnu.org/
